Question

( x + 2) ( x + 1 ) is this Quadratic polynomial ?????​

Answer 1

Answer:

$(x + 2)(x + 1) \\ \\ = {x}^{2} + x(2 + 1) + 2 \times 1 \\ \\ = {x}^{2} + 2x + x + 2 = {x}^{2} + 3x + 2$

☆Yes it is a quadratic polynomial ,it has got highest degree of variable as 2.

Answer 2

Answer:

( x + 2) ( x + 1 ) = 0

x(x+1) +2(x+1) = 0

x² + x +2x + 2 = 0

x² + 3x + 2 = 0

yes it is a quadratic polynomial because highest degree of this polynomial is 2
